Subject: [PATCH] allow opcache cross-compiling

Remove the check at the end of ext/opcache/config.m4 that prevents opcache from
being enabled in a cross-compiled environment. We pass the following as a
CFLAGS when opcache is enabled:
  -DHAVE_SHM_IPC
  -DHAVE_SHM_MMAP_ANON
  -DHAVE_SHM_MMAP_ZERO
  -DHAVE_SHM_MMAP_POSIX
  -DHAVE_SHM_MMAP_FILE
